Gene therapy tool developed by scientists for delivering DNA

Gene therapy has been able to create excitement in the world of medicine but it has not been regarded as a feasible therapeutic method up till now. One of the problems being faced is that how one could get right gene into the right area and that too at the right time. In order to tackle this problem, researchers are in the process of developing a tool for dealing with this problem and an ultrathin nanoscale film consisting of DNA and water soluble polymers has been created by researchers which would ensure controlled release of DNA from the surface. The film is created one layer at a time with the aid of dip coating method and since each layer is so thin around ten thousand layers are required for achieving the thickness of one paper sheet. As it turns out, making the DNA-containing films is relatively straightforward but getting the DNA back out of the films is the hard part. Via biologynews
